✦ Synopsis

Oscillographic polarography has been used to determine the diffusion coefficient of silver ion over a wide composition range of NaNO,-KNO, at 315, 340 and 360°C. Agreement of the polarographic diffusion coefficient with the chronopotentiometric diiusion coefficient has been found.

The Ag+ diffusion coefficient decreases with increasing concentration of KNO.. Such KN08 concentration dependence of the silver-ion diffusion coefficient can be explained by the Lumsden model.

By combining diffusion data with currently available transport values, such as electric conductivity and transference number, interionic friction coefficients can be calculated.
